Previously win_set_shadow tries to release the shadow image when turning off shadow for a window. When shadow is turned off _immediately_ after it's turned on, picom won't have a chance to handle the delayed creation of the shadow before win_set_shadow tries to release the shadow image, causing a assertion failure because win_set_shadow tried to release a non-existing image. This commit makes releasing the shadow image delayed as well. In theory, we could check the STALE flag in win_set_shadow before release the image, but that duplicates the logic that is already in win_process_flags. Signed-off-by: Yuxuan Shui <yshuiv7@gmail.com>
